Where do nightmares come from? Are they figments of our imagination, or physical beings that exist in our world? What if all of our dreams begin as pleasant ones, without a single bad dream to haunt our sleep. However as we sleep, there are creatures that come out at night and feed upon the positive energy and happy emotions in our dreams. As these creatures, these Nightmares, devour those feelings, they sustain themselves and survive, but our peaceful dreams are drained and corrupted, leaving behind only the twisted remains, the frightening visions that terrorize our sleep.
